Neymar needs to match the professionalism of Cristiano Ronaldo and Lionel Messi in order to achieve his full potential, according to Brazil great Zico.

Paris Saint-Germain superstar Neymar has scored 69 goals in 80 appearances in all competitions since arriving at the Parc des Princes from Barcelona for a world-record transfer fee of €222 million (£195m/$240m) in August 2017.

The 28-year-old has won every domestic title available in France but injuries, and now the coronavirus pandemic, have blighted his attempts to lead PSG to success in the Champions League.

Zico has no doubt about Neymar's talent, but feels he will be unable to reach the levels of Messi and Juventus star Ronaldo – who have won the Ballon d'Or 11 times between them – without changing his attitude.

"I really like Ney, his way of playing is incredible. But he has to be more professional like Ronaldo and Messi, who live for football," Zico told Gazzetta Dello Sport.
